SPINNING AND TWISTING FRAME.

SPECIFICATION forming part of Letters Patent N o. 658,154, dated September 18, 1,900.

Application filed April12, 1900. Serial No. 12,521. (No model.)

To a/ZZ whom t may concern:

Be it known that I, ARTHUR MASON, of Raynham, county of Bristol, State of Massachusetts, have invented an Improvement in Spinning and Twisting Frames, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to spinning and twisting machines; and it has for its object the pro duction of means ior holding the ring-rail in its lowest position to facilitate dotiing, while the thread-board is simultaneously maintained in raised position. The ring-rail is elevated by the usual overbalancing-weights, and as the rail is liable to be in any intermediate position when the frame is stopped for doiing it is necessary to force the rail down to its lowest point at such time, and in accordance with my invention the means for holding it at such point operate automatically when such depression is effected.

Figure l is a front elevation of a portion of a spinning or twisting frame embodying one form of my invention, the parts being shown by full lines in dofting position and by dotted lines in running position. Fig. 2 is a part end elevation of the mechanism shown in Fig. l, the end frame being broken out in places to show the parts beyond, with the parts in dofting position. Fig, 3 is a detachedview in elevation of the guide-bracket provided with a stop, to be described; and Fig.v 4 is a top or plan view of said bracket. 1

The end frames A, cross-girth AX, spindlerail RX, reciprocating ring-rail R, rockershaft H, having the attached lever H', the upright rocker-arm H 2,and its pivotally-connected link H3, the roll hX on the lever H to engage the lower end of the lifting-rod H4, the hinged thread-board B, and the arm 2O fast on the rocker-shaft and provided with the overbalancing-weight H may be and are all of usual or well-known construction in spinning and twisting frames.

The lever H/ is providedat its extremity with a footpiece or step H5 to depress the lever to its lowest point by pressure of the foot of the attendant when it is desired to doff, and the oppositely-extended weighted 10 of the frame, limiting the movement of* `saidlever when depressed by the foot.

As best shown in Fig. 2, the thread-board B has suitably secured thereto a lifting-handle b, provided with-a rigid depending bent arm b and a latch b2, pivoted at b3 on the enlarged part of the handle, said latch passing th rough a loop-like 'keeper b4 and shouldered at b5 to engage the keeper when the thread-board is lifted, as in full lines, and maintain the board locked in such position.

A chain or other iieXible connection cis attached to the end of the bent arm b and passes over a guide pulley or roll C, rotatably mounted on a suitable bracket CX, slotted at cx, Fig. 2, to receive a bolt l5, by which the lbracket is adjnstably secured to the frame.

The free depending end of the chain is attached by a preferably-adj ustable swivel connection c' with a vertically-movable slide D, shown as an elongated block longitudinally slotted at d and threaded at itsy upper end to receive the threaded shank of the swivel connection o', adjustment of either the bracket CX or said connection regulating the throw of the slide D, as may be necessary.

A bracket DX, having a laterally-o Ffset portion dx, is secured tothe inner face of the end frame by a suitable bolt 25, said bracket being recessed longitudinally to form side flanges d', which on their inner faces are grooved, as atdz, (see dotted lines, Fig. 1,) to receive and form guides for side ribs d3 on vthe slide D, said bracket having at its upper end an elongated projection or stop d4, which is extended through the slot d of the slide.

The slide D is herein shown as provided on its inner face, on opposite sides ofthe slot d,

with ears d5, in which is fulcrumed at d6 a l detent e, shown as a bar provided with an enlargement e at one end and having at its other end, movable between the ears, a camhead e2, hook-like in its general shape, said detent on.its upper side at the base of the head having a shoulder e? and at the extremity of the hook-like portion lateral stops or shoulders e4.

The link H3 is provided with an abutment h2o in alinement therewith and between the IOO rocker-arm I-I2 and the adjacent end frame, said abutment cooperating at times with the detent e, as will be described.

When the frame is in normal running condition, the thread-board, lifting-handle and connected parts, and the slide D are in dotted-line position, Figs. l and 2, and at such time the weight of the detent e will cause it to swing down into dotted-line position, limited by the engagement of the stops e4 with the under sides of the ears d5. When it is desired to doif, however, the frame is stopped, and the attendant depresses the lever H by pressure of the foot on the step H5, bringing the rocker-arm H2 and abutment h2o into fullline position, (best shown in Fig. 1,) and at the same time he grasps the lifting-handle and lifts the thread-board, the latch b2 then automatically engaging the keeper b4 to maintain the thread board lifted. Such movement of the liftinghandle, however, operates through the iieXible connection c to elevate the slide D, and as the cam-head e2 of the detent engages the under side of the stop dl the detent will be rocked on its fulcrum d, elevating the foot e' until the straight body e of the detent is in alinement wit-h the link H3, abutment 71.20, and fulcrum d6, and at such time the shoulder e3 will engage the end of the stop CZ* and prevent further swing of the detent. The locking device for the thread-board also acts through the intermediate connections to also lock the slide D and attached parts in full-line position, Figs. l

and 2, and when pressure on the step H5 is removed the abutment h2o engages the foot c' of the detent and is held thereby, the detent taking up the thrust of the rocker-arm H2, and the ring-rail is held in its lowest position while dofiing is effected. Thereafter the attendant again depresses the step or treadle I-I5 to remove the pressure from the detent, the thread-board is unlocked and lowered to its normal position by the handle h, and this permits the return of slide D and detent to normal inoperative position, and the frame is again in operative condition.

The lifting and locking of the thread-board and the locking of the ring-rail in dofng position are effected simultaneously and by or through a common actuator-the handle I). So far as I am aware this is broadly new and is a very decided and distinct advance in the practical construction and operation over devices heretofore devised for the purpose of dofing spinning or twisting frames.

My invention accordingly is not restricted to the precise construction and arrangement herein shown and described, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
